- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2015-0857, CVE-2015-0858.
- More information:
Several vulnerabilities were discovered in tardiff, a tarball comparison tool. The Common Vulnerabilities and Exposures project identifies the following problems:
Rainer Mueller and Florian Weimer discovered that tardiff is prone to shell command injections via shell meta-characters in filenames in tar files or via shell meta-characters in the tar filename itself.
Florian Weimer discovered that tardiff uses predictable temporary directories for unpacking tarballs. A malicious user can use this flaw to overwrite files with permissions of the user running the tardiff command line tool.
For the stable distribution (jessie), these problems have been fixed in version 0.1-2+deb8u2.
For the unstable distribution (sid), these problems have been fixed in version 0.1-5 and partially in earlier versions.
We recommend that you upgrade your tardiff packages.
